Teleport to Object not working
The active object needs to be on a visible layer in order for View Selected (.) to work.

Look in the 3D view header at the layers.


As shown in that picture, I suspect you will have the active object on a non visible layer. The darker squares are the visible layers. The orange dot is the active object.

Press ` to show all layers, or Shift LMB  on the layer button in the 3D view header for the layer the active object in on.
